A recipe calls for5oz of flour for every 4oz of milk. Let x be the amount of milk used. Let y be the amount of flour used. Express the relationship with an equation. Is the relationship proportional? If you use 14oz of milk, how much flour should you use?
Express the relationship with an equation.
Is the relationship between x and y proportional?
You should use ?oz of flour. ? For 14oz of milk.Simplify your answer. Write an integer,fraction,or mixed number
Flour/Milk = Y/X = 5/4.
a. Yes.
b. Y/X = 5/4, Y/14 = 5/4, Y = ?.
To express the relationship between x (milk used) and y (flour used) with an equation, we can use the given information that the recipe calls for 5oz of flour for every 4oz of milk.
The equation can be written as:
y = (5/4)x
This equation represents the relationship between the amount of milk used (x) and the amount of flour used (y).
Now let's determine if the relationship between x and y is proportional. For a relationship to be proportional, there must be a constant ratio between the two variables. In this case, we can see that the ratio between y (flour) and x (milk) is not constant, as it is not always 5/4. Therefore, the relationship is not proportional.
To find out how much flour should be used when 14oz of milk is used, we can substitute x = 14 into the equation:
y = (5/4) * 14
y = 17.5
So, when 14oz of milk is used, you should use 17.5oz of flour.
In simplified form, the answer is:
You should use 17 1/2 oz of flour for 14oz of milk.
